Shawn Nematbakhsh c366c20899 Hold I2C lock through entire PD read transaction

I2C reads from the PD happen in two separate transactions, but no stop
condition is set after the first transcation. Therefore, it is necessary
to lock the I2C bus across both transactions to prevent other tasks
from using the bus in between.

BUG=chrome-os-partner:29839
TEST=Manual on Samus. Boot to recovery screen, plug + unplug power
supply, verify that no I2C error messages are printed to console.
Then repeat 100x.
BRANCH=None.
